im using the last version of Ableton live 11, have a preset with some tracks that have Kontakt instruments and I use it to play live. for the third time this year I received this message when I open it "One or more Kontakt instances cannot be recalled correctly, perhaps due to missing content. Please open any Kontakt instance in your host, Komplete Kontrol or Maschine to resolve the issue." And now I have to rebuild all the preset again
